JIC Release No. 1 - Guam to Move to COR 3 at 5 pm; Tropical Depression Continues toward the Marianas

Governor Eddie Calvo and Rear Adm. Shoshana Chatfield, commander, Joint Region Marianas, anticipate placing Guam and the respective military bases in Condition of Readiness (COR) 3 at 5 p.m. this afternoon. At COR 3, damaging winds of 39-57 mph are expected within 48 hours.

The National Weather Service (NWS) – Guam Weather Forecast Office issued a tropical storm watch for Guam and Rota as Tropical Depression 34W moves toward the Marianas. A tropical storm watch means tropical storm conditions, including damaging winds of 39 mph or more are possible within the next 48 hours.

As of 1 p.m., the tropical depression was located 5.0 degrees north latitude and 155.1 degrees east longitude; about 280 miles southeast of Chuuk and 915 miles southeast of Guam, moving west-northwest at 13 mph with maximum sustained winds of 30 mph.

The tropical depression is expected to continue in this direction with a gradual increase in forward speed possibly becoming a tropical storm tonight. On its current track, the closest point if approach to Guam is around 200 miles southwest on Thursday afternoon as a typhoon.

The onset of damaging winds of 39 mph or more are possible on Thursday. The maximum sustained wind prediction for Guam is 35-40 mph with gusts to 45 mph. Rainfall amounts of 2-4 inches is possible during its passage but this could be higher or lower depending on the storm’s track.

Currently, possible impact for Guam is some downed limbs and vegetation, power lines can be affected, very light materials/signs can be blown around, tarps and canopies need to be well-secured, and moderate to strong rip currents are expected.

Mother Nature can be unpredictable so take some time to clear your yard and take other steps to prepare just in case the storm takes a northward turn. Those planning outdoor activities for Thanksgiving are advised to have plans in place to move indoors. Mariners should be prepared to secure craft if hazardous seas build.

To prepare for any scenario, residents and visitors are advised to:
  • Stay up to date with the latest information. The storm track or intensity may change and advisories regarding dangerous seas may be issued.
  • Locate or prepare your emergency preparedness kits for your household; stock up on non-perishable food items and water for your household, flashlights, first-aid kits, batteries, matches or lighters, portable stove, toiletries, etc. Visit https://www.ready.gov/build-a-kit for more information on what to include in your supplies list. 
  • Secure important documents such as birth certificates, tax papers, and insurance documents and keep copies in a water-proof bag. 
  • Clear loose debris and vegetation around your yard.
  • Safely secure any items that may become airborne with heavy winds such as wooden signs, canopies, tarps or trampolines, before inclement weather arrives.
  • Gas your vehicles and get fuel for your generators now while the weather is clear.
  • Those living in areas prone to flooding should be prepared to take action; clear drainage areas and un-block clogged storm drains in your area now to minimize the chance of flooding.
  • Once inclement weather arrives, avoid camping, parking, or hiking along streams, rivers, and creeks during heavy rainfall. These areas can flood quickly and with little warning.
